What you'll actually pay for Obamacare
Millions of Americans won't have to pay full price for their Obamacare health insurance next year. But just how much they'll have to fork over depends on a couple different things. Thanks to subsidies from the federal government, which will help pay for health insurance on state-based exchanges starting in 2014, many low- to moderate-income Americans will get a break on their premiums.

Where car ownership costs are most expensive
Driver beware. Car ownership costs can vary widely from state to state. For example driving a car in Georgia, the nation's costliest state to own a car, is about $2000 more expensive than driving the exact same car in Oregon, the nation's cheapest state, according to a new report from Bankrate.com, a personal finance website.

Want to save on college? Ditch dorms, campus
To lower the cost of college, more parents are suggesting that their kids skip dorm life, and perhaps even the campus altogether. According to a new study from Fidelity, 54% of parents expect their children to take online courses for credit. Half of parents say they're considering having their child live at home and commute. The number of students taking online courses has spiked. Since 2010, online college course enrollment has jumped 29%, according to Columbia University's Community College Research Center. Now, 6.7 million students (roughly a third of all college students) are enrolled in online courses.

Judge Judy is highest-paid TV star
Judge Judy is far and away the highest paid person on television, according to TV Guide's fifth annual list. Judge Judy Sheindlin gets paid $47 million per year to sassily chastise those locked in petty disputes on the daytime show that bears her name. Stephen Battaglio, TV Guide's business editor and author of the list said Judge Judy generates about $200 million in ad revenue for CBS but costs just $10 million per year to produce, before factoring in Sheindlin's salary. The show is aired internationally, and some stations air it several times a day. A spokesman for Judge Judy declined to comment.
